Concussion controversy as Tyrone’s Sean Cavanagh plays on after blow

Tyrone’s Sean Cavanagh remained on the pitch against Monaghan on Saturday night despite suffering from what his manager Mickey Harte termed afterwards as a "slight, mild concussion".

The GAA’s own protocols, published in a document entitled ‘Concussion Management Guidelines 2013-16’ clearly state that any players suspected of a concussive injury should be “removed from play” immediately.

The phrase in question is emphasised by being written in bold, block capitals and underlined.
